T 0 allavhom it may concern Be it known that LLours V. I'IOMAN, a citizen. of the United States, residingat SOlltllkDdItHlOllth, the county'of Bristol and State of Massachusetts, have invented new and. useful Improvements in Apparatus for Operating Gates,:&c., of which the following :is a specification.

This invention relates to a barrier such as a gate, arranged in a vertical plane and mounted to swing horizontally on a vertical axis, the gate being,:for example, a barrier across a driveway, and adapted to openand close the latter.

The invention has'forits object to pro vide means operable by; a' vehicle approaching the gate to open it, andby a vehicle leaving the opened gate to close it.

The invention 'isembodied in the improvements which I will now proceed'to describe and claim.

Of the accompanying drawings forming a part of this specification,.,

Figure -1 is a plan view-illustrating the invention conventionally 'or diagrammatically.

Fig.2 is av front elevation, showing the gate closed.

:Fig. 3 is a section on line 33 ofFig. 2, and a- ;plan View of parts below said line.

Fig. 4 is a sectional "view of one of the vehiclesoperated platforms and parts associated therewith.

Fig. 5 is a section on line 55;of Fig. 2.

Fig. 6 is a detail 'view showing the relation of the controlling arm to the motor, and to the oscillatory arm.

The same-reference characters indicate the same parts in all of the figures.

In the drawings, 12 represents 'a vertical post, adapted to berotated in-fixed bearings, the bearingswforthe lower end of the post being below a surface 13,:which may be the surface ofvadriveway. The bearings 14 for the upper-end of the post may be attached to a fixed post or standard 15.

To the post 12 is atta'cheda barrier, such as a gate 16, which maybe ofany suitable construction, and isadaptedto swing over the-surface'13 toopen-and close the latter.

.I providerotating means adapted to rotate face 13.

ling member whioh'is the-arm 20 of. a reversing switch, said arm projecting through the slot 19111 the casing. The motor. may be =fixed-within;ahousing 21 at one side of the driveway.

The motor constitutes an element ofa two-way post rotating means, whereby, the

.gate :may be opened and closed, themotor being rotated in a direction to open the gate when the arm .20 is moved, from one end of the slot 19, and rotated in the directionrequired'to close the gate when the arm 20 is moved to the opposite end of said slot. hen the arm 20 is, in the neutral position, or central between the ends of the slot 19, the motor isstopped.

The gate. post 12 is provided at its. lower end portion with a worm gear segment 22, which meshes with a worm 23, fixed to a horizontal rock-shaft 24, saidshaft being journale'd in suitable bearings below the sur- Torque-transmitting connections are provided between the motor-shaft 18 .and the rock-shaft 24, said connections as ahere shown, lncludinga sprocket-wheel25,

fixed in the motor-shaft, a sprocket-wheel .26 j ournaled in fixed bearings below the motor, a sprocket-wheel 27 fixed'to-therockshaft 24, and a sprocket-chain 28 connected with the 116618 25 and-26, and a sprocketchain 29 connecting the wheel 27 -with a smaller sprocket-wheel 30, which is =fixed to and coaxial with the wheels 26.

Located in the driveway at suitable points, are two platforms 31 and 32., which are normally raised, andadapted to be depressed by a vehicle-wheel bearing thereon. Eachv platform and the power-transmitting means form, and provided with a fixed spring abutment 44, and with a removable spring abutment 45 bearing on the lever 40, a spring 46 being interposed between the abutments 44 and 45. Yielding connections are thus provided between the platform 31 and the lever 40. The cable 39 is connected in like manner with the platform 32.

The platform 31 is located atone-side of the opening covered by the gate, and the platform'32 is located at the opposite side of said opening, the arrangement being such that when a wheel 47 y of a vehicle such as a motor car, is approaching the gate, it depresses the platform 31 and moves the oscillatory arm 35 to position to cause the motor to open the gate. When the vehicle has passed through the gate, and the wheel 47 bears on the platform 32, the motor is reversed and caused to close the gate.

After each opening and closing of the gate the motor is automatically stopped by means including two tappets 48 and 49. fixed to the post 12, a horizontal lever 50 fulcrumed at 51 and having one of its ends in the path of the tappets 48 and 49, and a rod 52 connecting the other arm of the lever 50 with the oscillatory arm 35. The arrangement is such that when the gate reaches one extreme of its movement, the tappet 48 causes the oscillatory arm 35 and controlling member 20 to assume the neutral position shown by Fig. 5, and when the gate reaches the other extreme of its movement, the tappet arm 49 performs the same function.

The cables 38 and 39 may be made in sections, adjustably' connected by turn-buckles 53, as shown by Fig. 5. Said cables are guided by suitable means, including shives or pulleys 54, and tubular conduits 55 located below the surface 13.

The gate may be composed of two leaves or sections 16 and 16*, as indicated by Figs.

1 and 2, in which case the rock-shaft 24 is elongated and provided with a worm 23 meshing with a worm-gear sector 22 on the post 12 of the gate section 16*, the direction of the threads of the worm 23 be-.

ing opposite to that of the worm 23, so that the two gate sections are swung simultaneousl in opposite directions.

hen a two-leaved gate is employed, the vehicleoperating means for opening and closing the gates will include another platform 31 having the same function as the platform 31, and another platform 32 having the same function as the platform 32.

I claim:

Gate-operating mechanism comprising, in combination, a reversible motor, a motordriven gate, torque-transmitting connections between the motor and the gate, and motorcontrolling mechanism operable by a vehicle approaching thegate to open the gate, and by a vehicle leaving the gate to close the gate, said mechanism including normally raised platforms located at opposite sides of the gate and depressible by vehicle wheels approaching and leaving the gate, a controlling member associated with the motor and adapted to occupy either of two operative positions and an intermediate neutral position, an oscillatory arm engaged with said controlling member, and adapted to move the latter to either of said positions, flexible connections between said platforms and said arm, and means operable by the gate when the latter reaches an open and a closed position, to move the oscillatory arm and controlling member to the neutral position of the latter, and thus stop the motor.

adapted to move the latter to either of said positions, flexible connections between said platforms and said arm, oppositely acting tappet arms, movable in opposite directions by the gate, and connections between said arms and the controlling member to move the latter to its neutral position and stop the motor when the gate reaches an open and a closed position.
